Prepare to remove NVMe PCIe SSD device
You can remove a Non-Volatile Memory Express (NVMe) Pheripheral Component Interconnect Express (PCIe) Solid State
Device (SSD) without shutting down or rebooting the system. When you are removing a device, all the activities associated with
the device must be stopped to prevent data loss. To prevent loss of data use the Prepare to Remove option, which stops all the
device-associated background activities, after which you can remove the NVMe PCIe SSD physically.
NOTE: Follow the VMware documented prerequisites before performing Prepare to Remove operation in VMware ESXi.
Remote iDRAC hard reset
iDRAC may become unresponsive due to various reasons. iSM can fully reset an unresponsive iDRAC8 or iDRAC9 controller by
temporarily removing power to the iDRAC controller without affecting operating system production. This feature can only be
disabled from the iDRAC Service Module page in iDRAC using any of the iDRAC interfaces.
To reset iDRAC, use the following Windows PowerShell or Linux shell command:
./Invoke-iDRACHardReset
NOTE: This feature only works with iDRAC8 on the 13
th
generation PowerEdge servers or later and if logged into the
operating system as an administrator.
iDRAC access via Host OS
Using Dell’s PowerEdge Servers, you can manage the hardware or the firmware of a device through iDRAC by configuring an
iDRAC dedicated network. Through the dedicated network port, you can access the iDRAC interfaces such as GUI, WSMAN,
RACADM, and Redfish client.
The prerequisite to manage the hardware or the firmware is to have a dedicated connection between a device and the
supported iDRAC interface. Using the iDRAC access via Host OS feature, you can connect to an iDRAC interface from an OS
IP or host irrespective of the connection between a device and an iDRAC dedicated network. This feature allows you to monitor
the hardware or firmware even if the iDRAC is not connected to the network.
You can select any of the following sub features to enable the iDRAC access via Host OS:
● Access via GUI, WS-man, Redfish, Remote Racadm
● In-band SNMP Traps
● Access via SNMP Get
If you select iDRAC access via Host OS, all the sub features are selected by default. If you want to select any one of the
individual sub feature, you can select a particular feature and enable it.
For more information, see iDRAC Access via Host OS whitepaper.
Accessing iDRAC Via GUI, WS-man, Redfish, Remote
RACADM
Access via GUI, WS-man, Redfish, Remote Racadm feature enables a Host OS administrator to access iDRAC interfaces
remotely via the Host OS. Type the URL https:// <Host OS IP Address>: <ListenPortNumber> in the browser of
the remote management station to access the iDRAC GUI.
NOTE: The ListenPortNumber is the port number configured while enabling the iDRACAccessviaHostOS feature in iSM.
In-band support for iDRAC SNMP alerts
Using iDRAC, an out-of-band server management and monitoring tool, the SNMP traps/alerts can be recorded in the log.
However, from a host OS systems management using in-band agent perspective, the preference is more on the SNMP alert
